Drugs like Darvon and Darvocet contains this chemical as its center bond and its overdose can result to be fatal.
The FDA is thus now on the prowl to control the release and use of these drugs. Every now or then there comes analgesics in the market which spread unregulated unless reports of fatal damage come to public concern.
Before the release of such drugs in the main stream use the FDA should have released cautionary reports on these. Now, recent reports all push propoxyphene towards being really damaging for human health in larger doses. This led FDA to take straight actions for the control of these medicines.
The latest manufacturing of these drugs will have labels that will read to be extra strong and they will have regulatory messages as well. These extra cautions are expected to raise awareness about the use of these analgesics.
